Reflections on Chinese residents' calcium intake and human health / 中华预防医学杂志

Calcium plays an important role in various physiological activities of the human body, and long-term insufficient or excessive intake of calcium will have a negative impact on the body's health. Existing data show that insufficient dietary calcium intake is closely related to bone health, but the non-bone effects are not clear. Increasing dietary calcium and supplementing calcium (with or without vitamin D) have a certain beneficial effect on the bone mineral density and its peak of adolescents and can delay the bone loss of the elderly, but it can't improve the height and bone mineral density of adults and fracture in the elderly. This article introduces the physiological functions of calcium, dietary sources, human intake, and methods for formulating recommended amounts, and summarizes the relationship between calcium and health effects. It also recommends that when formulating the reference intake of dietary calcium for Chinese residents, more consideration should be given to the data and information of the Chinese population, combined with the characteristics of Chinese residents' genetics, absorption and metabolism.

Bilateral Peripheral Facial Paralysis Combined with HIV Meningitis During Acute HIV-1 Infection: A Case Report / 中国医学科学杂志(英文版)

Here we reported a Chinese case of bilateral peripheral facial paralysis (PFP) in human immunodeficiency virusc (HIV) infected population. A 38-year-old homosexual male patient was referred to our hospital for bilateral facial paralysis. 21 days prior to admission he had developed high fever, chills, headache, fatigue, general malaise, nausea and vomiting. Neurological examination revealed bilateral ptosis of lower lip and cheeks, as well as failure of bilateral eyes closure. Analysis of cerebrospinal fluid (CSF) revealed pleocytosis, a marked rise of micro total protein and a marked rise of intrathecal lgG synthesis. The result of HIV-1 serology was positive by ELISA and that was confirmed by western blot. His CD4 cell count was 180 cells/mm . HIV-1 viral load in CSF was almost 10 times higher than that in plasma. The patient's condition improved steadily and experienced complete resolution of bilateral PFP after 2 months.
